The County of Lambton, in conjunction with Clean Harbors Canada Inc., hosts several HHW collections events each year. The events give Lambton County residents an opportunity to properly dispose of potentially dangerous waste from their homes and protect our environment at the same time. If hazardous products are thrown in with the regular garbage, it can injure sanitation workers and cause long-term environmental problems.
Bring your household derived hazardous wastes to the special depot, and it will be dealt with by experts, at no cost to you!
Household Hazardous Waste collection events
HHW Days take place at the Clean Harbors Canada Inc. site, 4090 Telfer Road in St. Clair Township in March, April, May, June, September, and October. See the Household Hazardous Waste flyer for event details.
Additionally, the County hosts two mobile HHW collection events each year - one in Sarnia (Saturday, June 7, 2025) and one in Lambton Shores (Saturday, October 4, 2025).

Expired marine flares
Clean Harbors will not accept expired flares through the County's HHW program, as explosives are on the list of unacceptable items.
Flares (pyrotechnics) are only valid for four years from the manufacture date, which is stamped on each flare.
Lambton OPP recommends boaters keep expired flares in a sealed plastic bag beneath new flares. These expired flares may still work in a time of emergency, although they may have lost some of their certified range. They will provide a back-up, should the new flares fail to attract the attention of others in an emergency.
